To all whom 'it may concern:

Be it known that I, CHARLEs B. SCHOEN- MEHL, a citizen of the UnitedStates, and resident of Waterbury, in the county of New Haven and Stateof Connecticut, have invented certain new and useful Improvements inBattery-Element Supports, of which the following is a specification.

My invention relates to the class of voltaic batteries which employ acompressed copper oXid plate as a negative electrode and a suitable Zincplate as a positive element.

The invention particularly refers to means, such as a metal frame forsuspending the said positive and negative plates from a battery coverwithin a jar so as to conveniently ada t them for use when submergedwithin a so ution contained within such a jar.

It is the pur ose of my invention to imrove in severa particulars uponsupporting frames for elements of this kind, namely, first by providingintegral means for the attachlnent of the lield wires to the frame;second to provide precautionary means to prevent short circuiting of theelements, one with the other when in use, and further to construct thedevice so that the Zinc plates may be rigidly and firmly, butinsulatively connected to the copper plates and in a manner that willprevent one from contacting with the other.

Upon the accompanying two sheets of drawings forming a part of thisspecification similar characters of reference denote like orcorresponding parts throughout the several ligures and of which,

Figure l, shows a side elevation of my improved battery elementsupporting frame attached to a commercial type of cover ready to be setinto a battery jar. Fig. 2, is a detached edge view of a part of thesupporting frame and connected elements. as seen from the right ofFig. 1. Fig. 3, is a central vertical cross section taken on line 3 8 ofFig. 1. Fig. 4, is a detached perspective view of the insulating blocksused intermediate of the negative and ositive plate electrodes. Fig. 5,is a side e evation one of the zinc plates removed. Fig. 6, is adetached plan view of a wire yoke forming a art of the modified form offrame shown in ig. 5, and Fig. 7, is a central vertical sectional viewsomewhat similar to Fig. 3, though illustrating a different constructionof frame, but with substantially the same sort of insulating blocks asused in the other figures of the drawing.

Referring in detail to the characters of reference marked u on thedrawings represents compresse oXid of copper plates constituting thenegative electrodes, and of which there may be one or more, arrangedabove each other, The negative plate electrodes may be of the usual orany preferred shape but adapted to be arranged within my improved frame,and to which the usual zinc or positive plate electrodes 11 are attachedon either side, and opposite to the faces of the negative plates.

My supporting frame is preferably formed of wire and sheet metalcombined, and comprises parallel side Wires 12-12 upon which the top andbottom channel cross pieces 13 are mounted. Then two negative plates areused as shown in Figs. 1 and 5, an additional intermediate cross piece14 is also used to support the lower part of the upper plate and theupper edge of the lower plate. The negative plates are supportedintermediate these cross pieces and side wires by means of nuts 15attached to the threaded ends of the side wires as shown. These sidewires are connected together by a transverse portion 16 disposed againstthe bottom cross pieces as shown in Fig. 5, forming a U shaped wireframe portion and having the clamping nuts 15 attached to the upperends, or said sides may be connected across the top as seen in Figs. 1,2, and 3, and in which instance the clamping nuts 15 would be applied tothe bottom. Intermediate of the top wire cross portion 16 of the wireframe, or in the cross yoke 17 if employed, l form an upwardly disposedloop 18 the Wire side portions of which are disposed upward at a rightangle to the cross of a modified form of supporting frame with i memberand parallel with each other, while the top part of the loo is straightacross and parallel to the top c annel cross piece 13, thereby forming asquare opening therethrough as shown in Fig. 5, for the reception of acorrespondingly shaped lug 19 upon the inner faces of the insulatingblocks 20. This loop obviously constitutes a part of the frame and isextended above the main part thereof in a way. to rigidly support theinsulating blocks in true alinement with' the. frame, and so that whenthe Zinc plates are attached against the blocks, they will be rigidlysupported and the lower ends prevented from swinging' against the sidesof the negative electrode. The blocks are both firmly clamped inposition by the bolt 21 and its nut together with the nuts 15 beforementioned upon the ends of the wire frame. In this respect it will beseen that the result is about the same if the wire part of the frame beformed of one piece as shown in Fig. 1, or of two pieces as shown inFigs. 5 and 7. In the latter case it will be seen that a U shaped wireframe is employed together with' a wire yoke 17 having eyes 22 formed inits end portions to receive the threaded ends of the side wires. I alsoform in the top part of the frame by the further bending of the wire anintegral eye 23 to which a suitable binding screw 24 is connected forthe attachment of the field wire 25.

The blocks 20 are alike in construction as will be seen from Figs. 3, 4and 5, and are shaped to fit up against the op osite sides of -theintermediate top part of t e frame and plate when assembled, in a Way toentirely inclose the uppermost part of the frame by the said blocksmeeting flush against each other across the top. This constructionprevents any sediment which may form upon the top surface of theinsulating blocks from short circuiting the elements, as might be thecase were the top part of loop 17 in the frame exposed. Consistent withthe above objects each of the above blocks are cut away across thebottom as at 26 to receive the channel strip 13, and also cut away alongeach inner side edge as at 27 to intersect with the upper transversegroove 28 which joint recesses in the blocks obviously serve to receiveand accommodate the loop portion of the frame.

The outer side face of each block contains a square recess 29 to receivea correspondingly shaped shoulder upon the inner face of the zinc plates11, and whereby the zines are held in place against edgewise movementwhen secured in plate by the bolt 21 when secured therethrough. Thisbolt alsoserves the further purpose of electrically connecting the twozines which in practice constitute one side or element of the battery,and are further obviously insulated from the negative element by theblocks before mentioned. 31 represents hangers the lower ends of whichare connected against the side of the zinc plates by means of the bolt21 beforeV mentioned, while the upper ends are provided with a holethrough which a bolt 30 is passed for the connection of the hangers to alug 33 of the cover 34. A binding nut 35 attached to this bolt alsoserves for the attachment of the field wire 36 as shown in Fig. 1. Inthis connection it will also be seen that the frame and electrodescarried therein are supported by this bolt and may readily be connectedor disconnected by means thereof.

Having thus described my invention what I claim and desire to secure byLettersPatent is 1. An electrode support for batteries comprising aframe including in part a wire top cross piece having its intermediateportion bent up and around to form an integral eye for the attachment ofa binding post.
